Slackline setups: I'm always learning more and more about them. It really is a blast and is a fantastic way to disguise physics as something fun. Here is a 180 foot setup that I was on a few weeks back. If you've got any questions, I'd be happy to try and answer. And, if I can't answer, I bet I could point you in the direction of a person with the right answer.
And here, ladies and gents, is a mantid. I have no clue what species he is because I'm rather ignorant when it comes to entomology, but my god is he gorgeous. I found him in the park where the line was set up. Did you know these guys have been around since the cretaceous! Well, I though it was rad.
